A sensation of movement in vision is called oscillopsia.
When it occurs vertically, it is described by the person as a rolling of the vision in front of them.
This sensation of movement in the vision causes a vertigo or dizziness.
Experience of rolling vision is due to a condition known as nystagmus or an involuntary rhythmic shaking or wobbling of the eyes (nystagmus may cause vertigo or dizziness like effects from the sensation of motion in the vision).
Nystagmus and oscillopsia are usually initial symptoms of neurological disease called Multiple Sclerosis.
Noticing these symptoms during the exercise time is probably due to the Uhthoff phenomenon, an exacerbation (worsening) of the patient's symptoms (visual and sensitivity changes) when exercising or when exposed to temperature change.
You are welcome!
Presence of vertigo, oscillopsia (an illusory motion of the seen world), and sensation of unbalance, suggest a lesion of the vestibular system (a sensory system that helps people to feel balanced and oriented in space, located in the inner ear).
Since these symptoms are noticed or made worse when exercising, a neurological disease, Multiple Sclerosis must be taken into consideration, too.
This is one of my symptoms in a list of MANY....and my doctor also said that she wants to rule out MS. I am going for an MRI this Friday. My mom has MS and she seems to be able to live with it. Everyone is different when it comes to MS but I would love to finally get a diagnosis rather than "fishing around" for other possible things. I have a list of about 30 symptoms that I live with everyday....it's so frustrating.
